摘要： The present invention is to allow prompt and reliable synchronization of belonging information management table even in environments where there is a possibility of receiving update notification information from a plurality of wireless base stations, without needing unnecessarily large traffic for synchronization of belonging information management table. Wireless base station stores belonging information management table, to which belonging information of a terminal belonging to the base station is associated with, to new/old judgment information for judgment of new/old of update. Belonging information update unit performs update of belonging information including the new/old judgment information thereof. Further, upon receiving update notification information from other wireless base station, the belonging information update unit updates the belonging information management table based on the update notification information. The update notification information includes at least updated portion in the belonging information and new/old judgment information.

摘要： A WMMR (301) is used as a wireless relay node in a wireless network connected to a backbone network including a multicast data packet distribution source. A route control unit (N03) establishes a multicast data packet transfer route based on unicast routes by making reference to an SWGT (20) based on received route control information and adding an entry to a multicast routing table (MRT) (10). A transfer control unit (N04) makes reference to the MRT (10) and makes a transfer to a directly connected transfer destination along the established multicast data packet transfer route by unicasting capable arrival confirmation and retransmission control as a transmission scheme in the data link layer.
摘要翻译： 在连接到包括多播数据分组源的骨干网的无线网络中，WMMR（301）被用作无线中继节点。 路由控制单元（N03）基于接收到的路由控制信息，通过参考SWGT（20）来建立基于单播路由的组播数据分组传送路由，并将条目添加到组播路由表（MRT）（10）。 传输控制单元（N04）参考MRT（10），并且通过在数据链路层中作为传输方式单播能够到达确认和重传控制，沿着建立的多播数据分组传送路由传送到直接连接的传送目的地 。

摘要： The route maintenance unit outputs a period setting request to the period setting unit when the communication unit normally receives a Hello packet for the first time. The period setting unit sets a link connection confirmation period in response to the period setting request and outputs the set period to the route maintenance unit. The route maintenance unit maintains a radio link between the radio device in which the route maintenance unit is provided and an adjacent device upon receiving a data packet other than a Hello packet from the adjacent radio device even if a Hello packet is not received in the link connection confirmation period. Consequently, route disconnection or switching occurs less often.
摘要翻译： 当通信单元首次正常接收到Hello分组时，路由维护单元向周期设置单元输出周期设置请求。 周期设定单元响应于周期设置请求设置链路连接确认周期，并将设置的周期输出到路线维护单元。 路由维护单元在从邻接无线设备接收到除了Hello报文以外的数据分组的情况下，即使没有在链路中接收到Hello分组，也保持在提供路由维护单元的无线设备与相邻设备之间的无线链路 连接确认期。 因此，路由断开或切换较少发生。

摘要： The use of a wireless interface is dynamically changeable according to connection states of stations belonging to access points. Therefore, limited wireless interfaces are efficiently utilized without requiring operation in which the user conducts a complex setting operation. First, connection states of stations belonging to access points are measured. Based on information of the connection states, the connection destination of a wireless connection unit of an access point under consideration is changed over between an access point and a station.

摘要： A wireless communication system allocates resource information used in performing wireless communication to wireless base stations in order not to generate interference between access-side wireless interfaces and backbone-side wireless interfaces. Each of the wireless base stations includes an access-side wireless interface for covering wireless terminal devices and a backbone-side wireless interface for connecting the wireless base stations with each other. The wireless base station allocates resource information that is common to the wireless base stations to the backbone-side wireless interface that performs the wireless communication between the wireless base stations, and allocates resource information that does not generate interference with the backbone-side wireless interface to the access-side wireless interface.
